ABSTRACT

A wig including a wig base having a wearing portion to be worn on a head; and a hair portion having hairs affixed to the wig base; the hair portion being cut such that at least one part of a first hair portion that is located on the head when the wig is worn on the head is configured to project toward the head.

TECHNICAL FIELD

The present invention relates to a wig and a method for producing thewig.

BACKGROUND ART

Wigs have been used for visually concealing a decrease in a wearer'shead hairs (making up a deficiency in a wearer's hair volume) or beingutilized as a fashion accessory.

Such wigs have been desired to be naturally fitted to a wearer's hairs(wearer's own hairs) so as not to exhibit an artificial appearance inwearing. In the light of such desire, a wig has been proposed whichincludes artificial downy hairs at a portion thereof corresponding to aportion of a wearer's head where short and downy hairs grow incomparison to the remaining parts of the wearer's head, such as thehairline of a wearer's forehead, a wearer's head portions around his orher ears, and a wearer's hairline along his or her neck (see e.g. PatentDocument 1).

DESCRIPTION OF EMBODIMENTS First Embodiment

Now, embodiments of the present invention will be described in referenceto the accompanying drawings. FIGS. 1(a) and (b) are schematic views ofthe wig according to a first embodiment. FIGS. 2(a) to (h) are schematicviews illustrating modifications of the shape of a wig base 10. FIG. 3is a schematic view illustrating portions of the wig according to thefirst embodiment.

FIG. 1(a) is a schematic view of the wig 1 seen from its rear side (sideof the wig worn on a user's head hairs). FIG. 1(b) is a schematic viewof the wig seen from its front side.

As illustrated in FIG. 1(a), the wig 1 includes the wig base 10, falsehairs 20 (hair portion), and a securing member 30 (wearing portion).

Although the illustrated wig 1 is of a type which partially covers auser's head, the present invention is also applicable to a type whichwholly covers a user's head. The wig 1 is applicable to both of a womanand a man.

The following explanation will be made such that a user's head is calleda “head He”, and his or her own hairs are called “his or her own hairsHai”. With regard to the front and rear sides of the wig 1, a side ofthe wig 1 that is seen by another person when the wig is worn on thehead He is called a “front side” while the side of the wig 1 that isopposite to the front side and is closer to the head He than the frontside is called a “rear side”. The wording “temperature” described lateris expressed in degrees centigrade. The wording “angular portion”described later means a sharp portion where two linear edges meettogether. Further, the wording “heart shape” means a shape with theentire outline inscribed inside an inverted triangle as in a heart shapemark in playing cards, which has a valley portion deeply recessed inwardin the vicinity of an upper central position, and a sharply projectingportion formed at a lower position opposite to the valley portion (forexample, see the portion denoted by reference 10 b in FIG. 2(c)) suchthat the shape is rounded as a whole.

The wording “valley portion deeply recessed inward” means an arearecessed inward so as to be rolled from both sides such that a leadingedge as the valley bottom is made sharp (for example, see the portiondenoted by reference 10 a in FIG. 2(c)). The wording “rounded as awhole” means having almost no linear area at the outer periphery andbeing delimited by a convex or concave curved portion.

The wig base 10 holds the false hairs 20 and the securing member 30.Preferably, the wig base 20 is light-weight and is excellent in airpermeability. In the illustrated embodiment, the wig base is supposed tobe made in the shape of a mesh (or a net).

There is no limitation to the material of the wig base 10. The wig basemay be made of silk or nylon (polyamide fiber) for example.

Preferably, the wig base 10 is wholly formed in a gently curved shapewith a bulge in the vicinity of a middle portion thereof so as to befitted to the head He of a user. When the wig 1 is formed in a smallsize, the wig base may be formed in a planar shape without trouble.

Although the wig base 10 has a surface 11 exposed when seen from therear side of the wig 1, the wig base is concealed by the false hairs 20when seen from the front side of the wig 1 as illustrated in FIG. 1(b).

The wig base 10 has an area with the false hairs 20 affixed thereto,which has an outer peripheral outline that is wholly rounded without anangular portion (in other words, is at least partially formed in anarcuate shape). In FIG. 1(a), the wig base is shown to be formed in asubstantially oval shape when viewed in a plan view (hereinbelow,explanation about the shape of the outer peripheral outline will be madeon the assumption that the shape is viewed in a plan view). On thesurface 11 of the wig base 10, the securing member 30 is disposed at acertain position or certain positions. In FIG. 1(a), the securing memberis shown to be disposed at one position in a substantially centralposition.

On the wig base 20, the false hairs 20 are affixed so as to extend andspread in a radial fashion.

As illustrated in FIGS. 2(a) to (h), the outer peripheral outline of thewig base 10 and the disposition arrangement of the securing member 30are variable. The wig base 10 and the securing member 30 areschematically illustrated in FIGS. 2(a) to (h), and the size ratiobetween both members is not limited to the ones illustrated in FIGS.2(a) to (h).

In FIG. 2(a), the wig base 10 is shown to be formed in a substantiallyoval shape as the outer peripheral outline. The wig base 10 has totallytwo securing members 30 disposed at respective opposite end portions soas to be spaced apart from each other. The two securing members 30 aredisposed on an imaginary straight line (see the dotted line in thisfigure) extending in a longitudinal direction of the wig base 10.

The securing members 30 may be disposed, being turned at a certain anglein a planar direction. The planar direction means lateral and verticaldirections when FIGS. 2(a) to (h) are viewed from the front.

For example, assuming that FIG. 2(a) illustrates a modification with 0degree, the securing members may be disposed, being turned in a rangefrom 0 degree to 180 degrees or 0 degree to −180 degrees. For example,the two securing members 30 may be disposed at different angles fromeach other in FIG. 2(a) (such that both securing members are disposed soas to be slant at 90 degrees from each other or to have a spacingtherebetween gradually increasing in a downward direction when viewed ina planar view, for example). In a case where both members are disposedat different angles from each other, even when a force, which is enoughto take off the wig base 10 (wig 1) worn on the head He, is applied toone of the securing members 30 for example, the other securing member 30disposed at a different disposition angle serves as resistance to reducethe possibility that the wig base 10 (wig 1) would be taken off from thehead He.

In FIG. 2(b), the wig base 10 is shown to be formed in a triangularshape as the outer peripheral outline so as to be a little bulged aswhole as in a cam, such as a flat cam, when viewed in a plan view. Thewig base 10 has totally four securing members 30 disposed at respectiveend portions so as to be spaced apart from one another. The foursecuring members 30 are disposed at the respective vertex portions of animaginary quadrangle (see the dotted lines in this figure). The shape ofa flat cam is also expressed as an oval shape, a rice ball shape or ateardrop shape. The shape modifications of the outer peripheral outlineof the wig base 10 include such an oval shape, a rice ball shape and ateardrop shape.

In FIG. 2(c), the wig base 10 is shown to be formed in a substantiallyheart shape as the outer peripheral outline so as to have a sharpleading edge 10 b formed at an edge portion opposite to an edge portionwith the valley portion 10 a formed therein such that the sharp leadingedge projects outward. The wig base 10 has totally three securingmembers 30 disposed at respective end portions so as to be spaced apartfrom one another. The three securing members 30 are disposed at therespective vertex portions of an imaginary triangle (see the dottedlines in this figure).

As already described, the false hairs 20 are affixed so as to extend andspread in a radial fashion from the wig base 10. Accordingly, in thecase of the wig base 10 with the valley portion 10 a illustrated in FIG.2(c), portions of the false hairs 20 adjacent to the valley portion 10 aextend so as to intersect one another (see the arrows in this figure).In this way, the density of the false hairs increases an area adjacentto the valley portion 10 a to enhance the feeling of volume in the wig.

The provision of the leading portion 10 b contributes to give naturalhair flow (natural stream) to the false hairs around the leading portion10 b in both left and right directions. For example, when the wig 1 isworn on a position adjacent to a whorl of hair on the back a user'shead, the wig can naturally cope with the whorl of hair in either one ofa clockwise direction and a counterclockwise direction.

FIGS. 2(d) and 2(e) illustrate variations of the modificationillustrated in FIG. 2(c), wherein the aspect ratio of the heart shape,the depth of the valley portion and the degree of sharpness in theprojecting leading portion are varied. As illustrated in these figures,many variations can be made to the aspect ratio of the heart shape, thedepth of the valley portion, the degree of sharpness in the projectingleading portion and so on. When the wig bases 10 illustrated in FIGS.2(d) and 2(e) are used, these wigs can achieve a similar advantage tothe wig base 10 illustrated in FIG. 2(c).

The wig base 10 illustrated in FIG. 2(e) is formed in a smooth shapewithout having a leading edge portion similar to the leading edgeportions 10 b illustrated in FIGS. 2(c) and 2(d), and has five securingmembers 30 disposed thereon. Four securing members 30 among the fivesecuring members are disposed at the vertex portions of an imaginaryquadrangle (see the dotted lines in this figure where the imaginaryquadrangle is trapezoidal), and the remaining one securing member 30 isdisposed within an imaginary quadrangular area. When the remaining onesecuring member is disposed at the center of gravity of the imaginaryquadrangle in this case, the wig base has a well-balanced appearance.

The wig base 10 illustrated in FIG. 2(e) is formed in a planar shapecomparatively approximate to a round shape. The wig base formed in sucha shape is suited to a wig covering a comparatively wide range of auser's head. The wig base illustrated in this figure is formed in acomparatively simple shape, achieving a reduction in production costs.

In FIG. 2(f), the wig base 10 is formed in a substantially gourd shapeas the outer peripheral outline. The wig base 10 has totally two valleyportions 10 a formed on left and right edges thereof. The valleyportions 10 a may be disposed so as to be laterally symmetrical to eachother or to be vertically apart and be offset from each other. Thevalley portions 10 a may be disposed on upper and lower edges, not theleft and right edges. The wig base 10 may have totally four valleyportions 10 a formed on upper, lower, left and right edges thereof. InFIG. 2(f), the wig base 10 is shown to have totally two securing members30 disposed at respective opposite end portions so as to be spaced apartfrom each other as in the modification illustrated in FIG. 2(a).

When the wig base 10 illustrated in FIG. 2(f) is used, the density ofthe false hairs increases in areas adjacent to the two valley portions10 a to enhance the feeling of volume in the wig. Even when parting ismade in the false hairs, the false hairs are difficult to be parted,mingling with a user's own hairs Hai in a natural fashion.

FIGS. 2(g) and 2(h) illustrate further variations of the wig base 10,wherein the wig bases have such an outer peripheral outline that pluralwig bases 10 in a substantially oval shape as in the wig baseillustrated in FIG. 2(a) are prepared, are placed one after another,being shifted by a certain angle of turn, and are merged at outerperipheral edges.

Specifically, the wig base 10 illustrated in FIG. 2(g) is wholly formedin such a substantially throwing knife shape that two wig bases 10formed as in the wig base illustrated in FIG. 2(a) are prepared, one ofthem is placed on the other, being turned at an angle of about 90degrees, and are merged at outer peripheral edges. The wig base 10illustrated in FIG. 2(g) has totally four securing members 30 disposedat respective end portions so as to be spaced apart from one another.The four securing members 30 are disposed at the respective vertexportions of an imaginary quadrangle (not shown) as in the wig baseillustrated in FIG. 2(b).

The wig base 10 illustrated in FIG. 2(g) is allowed not only to increasethe number of the valley portions 10 a but also to dispose the valleyportions with good balance in comparison with the wig bases 10illustrated in FIG. 2(c) and so on. In this way, the variationillustrated in this figure is allowed not only to increase the number ofthe locations capable of achieving the advantage by the valley portions10 a but also to neatly organize the valley portions in appearance.

The wig base 10 illustrated in FIG. 2(h) is formed in such a shape thatfour wig bases 10 formed as in the wig base illustrate in FIG. 2(a) areprepared, the four wig bases are placed one after another, being shiftedby an angle of about 45° and are merged at a peripheral edges. The wigbase 10 illustrated in FIG. 2(g) has totally four securing members 30disposed at end portions, respectively. The four securing members 30 aredisposed at the respective vertex portions of an imaginary quadrangle(not shown) as in the wig base illustrated in FIG. 2(b).

The use of the wig base 10 illustrated in FIG. 2(h) achieves a similaradvantage to the wig base 10 illustrated in FIG. 2(g).

This is an explanation of the wig base 10. The outer peripheral outlineof the wig base 10 and the disposition arrangement of the securingmember(s) 30 are variable. For example, each of the outer peripheraloutline shapes and each of the disposition arrangements of the securingmember(s) 30 illustrated in FIGS. 2(a) to (h) may be combined. The outerperipheral outline in each of the modifications illustrated in FIG. 2(a)to (h) may be partially mixing.

For example, the modification illustrated in FIG. 2(a) may have theouter peripheral outline partially missing so as to be formed in asubstantially crescent shape, or the modification illustrated in FIG.2(c) may be halved to be formed in a half heart shape. For example, thewig base may be formed in a shape suggestive of a maple-like leaf or ashape of the spade or clover marks playing cards. When the outerperipheral outline of the wig base 10 is formed as explained above, itis also possible to enhance designability.

The false hairs 20 may be, for example, human hairs, artificial hairs ormixed hairs with human hairs and false hairs combined together and beaffixed to the wig base 10 by a known affixing method. The false hairs20 may be animal hairs in some cases.

The artificial hairs may be made of an acrylic material, chemicalfibers, a nylon material or the like, the use of which has an advantageof easily reducing the weight of the wig 1. The human hairs have anadvantage of giving a more natural appearance or feeling of touch to aviewer. The mixed hairs have both advantages achieved by artificialhairs and human hairs. The animal hairs have an advantage of easilyreducing the production costs of the wig 1.

As illustrated in FIG. 3, at least some portions of the false hairs 20(first hair portion) on the rear side of the wig 1 are formed so as topop out (fuzz up) toward the head He (hereinbelow, also referred to suchpop-out portions as fuzzy portions F). Reference symbol “Sc” in FIG. 3means the scalp of a user (also applicable to FIG. 5).

Each of the fuzzy portions F may include a single independent false hair20 or plural false hairs gathering together.

The fuzzy portions F may be formed by tapering false hairs 20. Taperingis a technique for shaving hairs by use of a cutter, such as a shavingrazor (hereinbelow, also referred to razor). For example, hairs are cutso as to gradually increase the shaving amount of false hairs 20 on therear side from their roots toward their tips. Tapering is also calledtaper cut in some cases.

Now, a specific example of the formation of the fuzzy portions F bytapering will be described.

(1) A hair panel (plate-like buddle of hairs taken out for tapering) isprepared while false hairs 20 are combed.

(2) A razor blade is brought into close contact with a surface of thehair panel (surface with a fuzzy portion F of the false hairs 20 formedthereon) while a certain tension is applied to the heir panel from theroot toward the tip of the hair panel.

(3) The false hairs 20 are cut at a certain length while the razor bladeis being moved toward the tips, being brought into close contact withthe false hairs 20. While the razor blade is being moved, it ispreferred that the angle included between the razor blade and the falsehairs 20 (inclination angle at which the razor blade raises from thefalse hairs 20) be kept constant. The angle is preferably at least 10degrees and at most 35 degrees, more preferably at least 20 degrees andat most 32 degrees, furthermore preferably at least 28.5 degrees and atmost 29.5 degrees.

(4) Thus, the cut false hairs 20 pop out.

(5) Steps (1) to (4) are repeated until the fuzzy portions F are formedin a certain mount.

Tapering may be applied to false hairs 20 affixed on the wig base 10 orbe applied to false hairs 20 before the false hairs are affixed. In thelatter case, the false hairs 20 are affixed to the wig base 10 aftertapering. The securing members 30 may be disposed on the wig base 10after tapering or before tapering. In other words, there is noparticular limitation to the order of the step for tapering false hairs20, the step for affixing the false hairs 20 to the wig base 10 and thestep for disposing the securing members 30 on the wig base 10.

The technique used for forming the fuzzy portions F is not limited totapering. Various kinds of techniques, such as setting-cut orpointing-cut, may be applied. These techniques may be used incombination. Scissors may be used instead of a razor.

The securing member or securing members 30 will be described in detailin reference to FIGS. 4(a) to (d). FIGS. 4(a) to (d) illustrateschematic views of a securing member 30 of the wig according to thefirst embodiment. FIG. 4(a) illustrates a front view of the securingmember 30. FIG. 4(b) illustrates an enlarged cross-sectional view takenalong line A-A in FIG. 4(a), wherein the securing member 30 is shown tobe in a state of being curved in a concave shape (state of being worn ona user's hairs). FIG. 4(c) is an enlarged cross-sectional view takenalong line A-A in FIG. 4(a), wherein the securing member 30 is shown tobe in a state of being curved in a convex shape (state of being out ofengagement with the user's hairs). FIG. 4(d) illustrates an enlargedview of a leading edge portion of a comb-like member 33.

As illustrated in FIG. 4(a), the securing member 30 includes a curvedplate member 31, an elastic member 32 and the comb-like member 33.

The curved plate member 31 is attached to the wig base 10, resulting inthe securing member 30 being mounted to the wig base 10. There is noparticular limitation to the method for attaching the curved platemember 31 to the wig base 10. The curved plate member 31 may be attachedto the wig base 10 by a desired method, such as sawing, fixing by use ofan adhesive or fixing by use of an eyelet.

The curved plate member 31 is a flexible flat plate transformablebetween the concave shape and the convex shape and is configured to havea space 310 formed in a middle portion so as to be surround by aperipheral edge portion 311.

The elastic member 32 is disposed on the peripheral edge portion 311 ofthe curved plate member 31 as illustrated in FIG. 4(a) and so on. Inthis embodiment, the elastic member 32 is disposed on a side of theperipheral edge portion 311 where the leading edge portion of thecomb-like member 33 is located. The elastic member 32 is disposed to bebrought into pressure contact with the comb-like member 33 in order toincrease the clamping force between both members during pressure contactwhen the comb-like member 33 is pressed against the curved plate member31 as illustrated in FIG. 4(b).

The provision of the elastic member 32 is helpful to reduce thepossibility that the wig 1 could damage a user's own hairs Hai at thetime of wearing. There is no particular limitation to the material ofthe elastic member 32. The elastic member may be made of millablesilicone rubber for example.

The comb-like member 33 includes a plurality of flexible bars 330 havinga small diameter. For easy understanding of the figure, only some of thebars 330 among all bars are denoted by reference numeral “330”. The bars330 are disposed in a width direction orthogonal to a longitudinaldirection of the curved plate member 31 so as to be side by side andapart from each other at the certain intervals. Each of the bars 330 hasa base end portion supported in a cantilever manner, fixed to one side311 a of both sides opposed across the space 310 in the peripheral edgeportion 311. Each of the bars 330 has a leading edge formed in aspherical shape. Since the leading edge is formed in a spherical shape,it is possible to reduce the possibility that a scalp with the wig 1thereon would be scratched, for example, when the wig 1 is worn on thehead He, or the wig is taken off from the head He.

When the curved plate member 31 is curved in a concave shape asillustrated in shown in FIG. 4(b), the comb-like member 33 is pressedagainst to the curved plate member 31 to bring partial surfaces of theleading edge portions of the bars 330 into close contact with theelastic member 32.

In contrast, when the curved plate member 31 is inverted into a convexshape as illustrated in FIG. 4(c), the comb-like member 33 is out ofpressure engagement with the curved plate member 31 with the result thatthe bars 330 move in a direction away from the curved plate member 31,being pivoted about the base end portions of the bars. In this case, agap 34 is formed between the comb-like member 33 and the curved platemember 31.

Although each of the bars 330 may extend straight from its base endportion, each of the bars is bent at its middle portion in thisembodiment. Each of the bars is bent as described to improve theclamping force in the state illustrated in FIG. 4(b) and reduce a localpressure to a user's head He as much as possible.

Each of the bars 330 has such a layered structure that the leadingportion including the leading edge formed in the spherical shape ispartly coated with a coating material 331 as illustrated in FIG. 4(d).Although not shown, each of the bars 330 has a synthetic resin layer(such as a silicone resin layer) interposed between each of the bars 330and the coating material 331 to fix the coating material 331 to each ofthe bars 330.

There is no limitation to where coating should be made with the coatingmaterial 331. For example, each of the bars 330 may have only thespherical portion of its leading edge portion coated, may be coated atits portion between the spherical portion of its leading edge and an endedge portion of the elastic member 32 (portion located in the space 310and facing 311 a in FIG. 4(a)), or may have wholly coated. Further, thecurved plate member 31 may be coated together with the bars.

The coating material 331 contains at least silk powder and/orfar-infrared ray ore powder.

As specific examples of the coating material 331, explanation will bemade about a case where the coating material 331 contains silk powder(in other words, the coating material 331 is almost wholly made of silkpowder), a case where the coating material contains far-infrared ray orepowder (in other words, the coating material 331 is almost wholly madeof far-infrared ray ore powder), and a case where the coating materialis made of silk powder and far-infrared ray ore powder.

(Case Where Silk Powder is Used)

When silk powder is used as the coating material 331, a silicone resinis applied to the comb-like member 33 by a certain length from theleading spherical portions (such as a length from the leading sphericalportions to portions facing the end edge portion of the elastic member32), followed by coating the resin-applied surface with the silk powder.

The silk powder has a particle size of preferably at least 50 mesh pass,more preferably 100 mesh pass. The term “mesh pass” means a mesh size(the size of openings of a sieve for screening granular substances (ASTMstandards)). For example, 50 mesh pass means that the particles of silkpowder pass through a sieve with 50 mesh. As the value of the mesh sizeincreases, the size of the openings of a sieve decreases. The mesh sizeis convertible to the size of the openings of a sieve according to theJIS standards. For example, 50 mesh size is equivalent to 300 μm.

As the particle size of silk powder decreases, the coating material 331of the silk powder becomes smoother to appropriately reduce thepossibility that a user's own hairs Hai could be damaged by beingbrought into contact with the bars.

(Case Where Far-Infrared Ray Ore Powder is Used)

Far-infrared ore powder is ore powder, which is excellent infar-infrared ray radiation at a room temperature (RT) to about at 40° C.

When far-infrared ray ore powder is used as the coating material 331, asilicone resin is applied to the comb-like member 33 by a length fromthe leading spherical portion to a certain portion (such as a lengthfrom the leading spherical portions to portions facing the end edgeportion of the elastic member 32), followed by coating theresin-applied-surface with the far-infrared ray ore powder and coatingthe far-infrared ray ore powder applied-surface with the silicone resin.

The far-infrared ray ore powder preferably has infrared radiation energy(in integral value) in a wavelength region of 2 to 25 (μm), which is atleast 320(W/m²) and at most 462 (W/m²) (equal to the infrared rayradiation energy of an ideal black body (full radiator) in the samewavelength region). The infrared ray radiation energy more preferablyhas a lower limit of at least 422 (W/m²).

As the level of the infrared ray radiation energy increases (approachesto that of the infrared ray radiation energy of a black body), it ispossible to appropriately enhance the blood flow in the scalp of thehead He. From this point of view, the far-infrared ray radiation orepowder has a radiation rate (ratio of the infrared ray radiation energyto a black body, represented by % here) of at least about 70%, morepreferably a value closer to 100%.

The far-infrared ray ore powder has a particle size of preferably atleast 50 [Me-pass], more preferably 100 [Me-pass]. As the particle sizeof the far-infrared ray ore powder decreases, the coating material 331made of the far-infrared ray ore powder becomes smoother to make iteasier to have a beautiful appearance.

The far-infrared ray ore powder can emit far-infrared rays to increasethe blood flow in the scalp of the head He. Thus, it is possible toprevent hair loss and to promote hair growth. As described above, thefar-infrared ray ore powder can be coated with the silicone resin toappropriately reduce the possibility that a user's own hairs Hai couldbe damaged by being brought into contact with the far-infrared ray orepowder.

(Case Where Silk Powder and Far-Infrared Ray Ore Powder are Used)

When silk powder and far-infrared ray ore powder are used as the coatingmaterial 331, a silicone resin is applied to the comb-like member 33 bya length from the spherical portion to a certain portion (such as alength from the leading spherical portions to portions facing the endedge portion of the elastic member 32), followed by coating theresin-applied surface with the far-infrared ray ore powder, applying thesilicone resin to the powder-applied surface and coating theresin-applied surface with the silk powder. Thus, it is possible to haveboth of the advantage offered by the use of the silk powder and theadvantage offered by the use of far-infrared ray ore powder, which aredescribed above.

Now, explanation will be made about how to use the first embodiment inreference to FIG. 5. FIG. 5 is a schematic view illustrating how to usethe wig according to the first embodiment. In FIG. 5, only a portion ofthe wig 1 is illustrated for simple visual comprehension. In thefollowing explanation, FIGS. 4(a) to (d) and so on are also referred toas needed.

First, a user sets the securing member 30 so as to have the curved platemember 31 inverted and curved into a convex shape to open the comb-likemember 33 as illustrated in FIG. 4(c), puts the wig 1 on a portion ofhis or her head He to wear and close the securing member 30 asillustrated in FIG. 4(b). Thus, the wig 1 is worn on the head He.

The user causes his or her own hairs Hai and the false hairs 20 tomingle by use of a hand or comb, placing both types of hairs in a statewithout a sense of incompatibility in appearance. In this state, thefuzzy portions F come into between his or her own hairs Hai, overlap hisor her own hair or get entangled with his or her own hair.

As described above, the wig 1 according to this embodiment of thepresent invention is characterized to include a wig base (wig base 10)having a wearing portion (securing member 30) to be worn on a head He,and a hair portion (false hairs 20) having hairs (false hairs) affixedto the wig base, wherein the hair portion is cut such that at least onepart of a first hair portion that is located on the head (rear side ofthe wig base) when the wig is worn on the head (ones of the false hairs20 that are located on the rear side) is configured to project towardthe head.

At least one part of the first hair portion (ones of the false hairs 20located on the rear side) is cut so as to be configured to projecttoward the head. The false hairs 20 thus cut on the rear side (fuzzyportions F) come into his or her own hairs Hai, overlap with his or herown hairs Hai or get entangled with his or her own hairs Hai with theresult that the false hairs 20 and his or her own hairs Hai becomedifficult to separate from each other to reduce the possibility thatfalse hairs 20 would lift from his or her own hairs Hai. Thus, it ispossible to effectively reduce that wearing of the wig would appear tobe unnatural.

The wig base 10 according to the present invention is characterized tohave an area with false hairs affixed thereto, which has an outerperipheral outline that is at least partially formed in an acute shape.The outer peripheral outline in an acute shape is compatible with thecurved surface of a user's head He to reduce the possibility that thewig base 10 would unnaturally lift from his or her own hairs.

The wearing portion (securing member 30) is characterized to clamp hairsto wear the wearing portion thereon (user's own hairs Hai) and has aprotection layer (coating material 331) formed at least partly thereonto protect the hairs to wear the wearing portion thereon (user's ownhairs Hai). The provision of the coating material 331 can reduce thepossibility that the user's hairs or scalp would be damaged when usingthe wig 1.

The wig base 10 may have the wearing portion (securing member 30)disposed at two or more positions. When the wearing portion (securingmember 30) is disposed at two or more portions, the wig 1 can bereliably worn.

The present invention is also characterized to provide a methodincluding a step for preparing a wearing portion to be worn on a head He(securing member 30), a step for preparing a wig base (wig base 10), thewig base being to have the wearing portion attached thereto, a step forattaching the wearing portion to the wig base, a step for preparinghairs (false hairs 20), a step for affixing the hairs to the wig base,and a step for cutting the hairs such that at least one portion of hairsthat are located on the head when the wig is worn on the head isconfigured to project toward the head.

(With Regard to Variations)

As described above, the explanation has been made about the firstembodiment of the present invention. Various variations are applicableto the present invention. Now, some variations of the present inventionwill be described.

(Variation 1)

FIG. 6 is a schematic view of the wig according to variation 1 of thepresent invention. The present invention encompasses a type of wig 2having a narrow width as illustrated in FIG. 6.

The wig 2 is of a type which has a limited covering portion of the headHe of a user in comparison with the wig 1 according to the firstembodiment of the present invention. This wig can provide hairs with afashionable impression at a one point.

Although the wig 2 has a wig base 10 exposed on the premise that the wigbase 10 is concealed by a user's own hairs Hai, the wig may beconfigured so as to have the wig base 10 concealed by false hairs 20 asillustrated in FIG. 1(b). The wig 2 is worn on the head He by a securingmember 30 as in the wig 1.

(Variation 2)

FIG. 7(a) to (d) are schematic views illustrating the wig according tovariation 2 of the present invention. FIGS. 7(a) to (d) schematicallydepict false hairs 20 in outline for simple visual comprehension. Itshould be noted that variation 2 of the present invention illustrated inFIGS. 7(a) to (d) is applicable to both of wig 1 illustrated in FIGS.1(a) and (b) and so on, and wig 2 illustrated in FIG. 6.

As illustrated in FIGS. 7(a) to (d), the wig may have a fuzzy portion Flocally disposed thereon. For example, the fuzzy portion F may bedisposed at a position close to the roots of the false hairs 20 asillustrated in FIG. 7(a), or the fuzzy portion F may be disposed at aposition close to the roots of the false hairs and a position close tothe tips of the false hairs as illustrated in FIG. 7(b).

The fuzzy portion F may be disposed at an intermediate position betweenthe roots and the tips of the false hairs 20 as illustrated in FIG. 7(c)or at a position close to the tips of the false hairs as illustrated inFIG. 7(d). The false hairs are firmly affixed to the head He at theirroots by a securing member 30 (not shown). In light of this reason, in acase where the fuzzy portion F is locally deposed, when the fuzzyportion is disposed at a position apart from the securing member 30, inother words, a position closer to the tips than the roots, it ispossible to appropriately reduce the possibility that the wig would liftfrom a user's own hairs or shift from the wearing position to causewig-wearing to appear to be unnatural.

(Variation 3)

FIGS. 8(a) to (c) are schematic views illustrating the wig according tovariation 3 of the present invention. FIGS. 8(a) to (c) schematicallydepict false hairs 20 in outline for simple visual comprehension as inFIGS. 7(a) to (d). Variation 3 of the present invention illustrated inFIGS. 8(a) to (c) is applicable to both the wig 1 illustrated in FIGS.1(a) and (b) and so on, and the wig 2 illustrated in FIG. 6.

As illustrated in FIGS. 8(a) to (c), the wig may have a fuzzy portion Fprojecting by locally varying lengths. For example, the fuzzy portionmay be formed so as to have longer lengths gradually from the tipstoward the roots of the false hairs 20 as illustrated in FIG. 8(a), tohave longer lengths gradually from the tips toward the roots, followedby having extremely short lengths and having longer lengths toward thetips as illustrated in FIG. 8(b), or to have shorter lengths graduallyfrom the tips toward the roots, followed by becoming gradually longer asillustrated in FIG. 8(c). The formation position or positions of thefuzzy portion F illustrated in FIGS. 8(a) to (c) are examples, and thepresent invention is not particularly limited to the illustrated modes.The present invention encompasses a pattern where the fuzzy portion F iswholly formed along the length direction of the false hairs 20 asillustrated in FIG. 3 or FIG. 6, and a pattern illustrated in each ofFIGS. 7(a) to (d).

(Other Modifications)

The present invention is applicable not only to the above-mentioned wigsbut also to hair extensions (hereinbelow, referred to as extensions) tobe attached at a hair salon or the like. Extensions have been recentlyavailable which are sold by mail order or the like, instead of being notattached at a hair salon, and are easily bought and worn by a user.Detailed explanation about such extensions will be omitted because suchextensions correspond to the wig 2 according to variation 1 illustratedin FIG. 6.

EXAMPLE 1

The inventors had each of two subjects (subject 1: 50 years old male,subject 2: 46 years old female) wear sample A and sample B as thesecuring member 30, and sample C as a securing member for comparison toconduct an inspection to see whether the provision of the coatingmaterial 331 would be helpful to reduce the damage to his hairs andscalp and her hairs and scalp. Further, a portion of his head with nosecuring member thereon and a portion of her head with no securingmember thereon were used as samples D, and an inspection about suchpotions as samples D was also conducted. It should be noted that thepresent invention is not limited to the examples.

First, samples A to D will be described in detail.

(Sample A)

A silicone resin were applied to a comb-like member 33 by a length fromthe spherical leading portions to portions facing the end edge portionof the elastic member 32, followed by coating the resin-applied surfacewith silk powder (having a particle size of 100 Me-pass).

(Sample B)

A silicone resin was applied to a comb-like member 33 by a length fromits spherical leading portions to portions facing the end edge portionof the elastic member 32, followed by coating the resin-applied surfacewith far-infrared ray ore powder (having a particle size of 100 Me-pass)and coating the ore powder-applied surface with a silicone resin. Thefar-infrared ray ore powder of sample B had infrared radiation energy(integral value) of 422 [W/m²] in a wavelength region of 2 to 25 [μm].An ideal black body (full radiator) has infrared radiation energy of 462[W/m²], and the far-infrared ray ore powder of sample B has radiationrate of 91 [%].

(Sample C)

This sample was a securing member, which had a surface coated with thesilicone resin without the application of another coating made of, e.g.silk powder or far-infrared ray ore powder used in the above-mentionedsample A or sample B.

(Sample D)

These samples were portions of the subjects' heads with no securingmember worn thereon.

<With Regard to Inspection>

FIG. 9 is a schematic view of a subject's head seen from the head top.The hair inspection and the scalp inspection were performed, having eachof the subjects where sample A, sample B and sample C were worn onrespective positions of his or her head as illustrated in FIG. 9. Inother words, the wearing positions were a right front vertex for sampleA, a left front vertex for sample B, a right occiput for sample C and aright occiput for sample D. The sample D was positioned on a leftocciput.

The procedure steps in the hair inspection and the scalp inspection willbe described in detail.

(Procedure Step 1)

It was confirmed that the two subjects had no problem with his or herscalp and hairs. The use of a hair tonic shampoo, a hair growing agentor the like was prohibited, having spicy food was limited, and thesubjects were encouraged to take a sleep for a period of time suited tothem in a period required for normalizing their scalp before inspectionto conduct preparation with their physical conditions taken intoconsideration.

(Procedure Step 2)

On the date of inspection, the two subjects were standby, sitting onchairs for about 10 minutes in a room having a room temperature of 25°C. and a humidity of 50% to be acclimated (accustomed) to theenvironment in the inspection room.

(Procedure Step 3)

Hair and scalp inspections were performed on the planned wearingpositions illustrated in FIG. 9 before the subjects wore sample A and soon after completion of acclimation. The hair inspection was performed,using an optical microscope in a replica method. Hereinbelow, the imagesto be explained were taken with the magnification of the opticalmicroscope being set to 100 times.

A hair has a layered structure including a hair medulla, a hair cortex(cortex) and a hair cuticle (cuticle pili or outermost layer of a hair)from a center toward the outside. In the hair inspection, the state ofthe cuticle in the layered structure was inspected.

The “hair cuticle” is a portion covering the surface of a hair, which ishelpful to protect the inside of the hair from an external stimulus andto prevent the protein and the moisture in the hair cortex from beinglost. The hair cuticle is configured such that normally six to eightextremely thin cells were brought into close contact so as to overlap ina scale-like manner (scale-like pattern) and in layers from the roottoward the tip.

The hair cuticle includes, as its component, keratin (rigid protein)having much sulfur content. Although the hair cuticle is rigid, the haircuticle is likely to be damaged or peeled by application of an excessiveforce, such as brushing, because of being brittle and being susceptibleto friction. A heathy hair has a scale-like pattern formed so as to beregularly arrayed in a wavy shape while a damaged hair has a scale-likepattern disturbed.

The scalp inspection was performed by use of a microscope (magnificationdisplay device including a high pixel color camera, lighting, lenseshaving different magnifying powers, connection cables and so on) and athermography camera. The images to be explained hereinbelow were takenwith the magnification of a microscope being set to 50 times. As thethermography camera, a product was used, which was available under theproduct name of TVS-700 manufactured by Nippon Avionics Co., Ltd.

(Procedure Step 4)

The two subjects passed the time, wearing sample A, sample B and sampleC, in a room prepared for them. At that time, they were allowed tofreely move around in the room while they were prohibited from going outor doing a heavy physical activity, such as sweating.

(Procedure Step 5)

After the lapse of about 5 hours and the lapse of about 10 hours sincesample A, sample B and sample C were worn, the same step as procedurestep 2 was taken to perform acclimation, and the same step as procedurestep 3 was taken to perform the hair and scalp inspections.

Results of the hair and scalp inspections are shown in FIG. 10(a) toFIG. 21(b).

First, the results of the hair inspection by use of an electronicmicroscope will be described in reference to FIG. 10(a) to FIG. 13(b).

FIGS. 10(a) and (b) and FIGS. 11(a) and (b) illustrate the results ofthe hair inspection for subject 1 (50 years old male). FIG. 10(a)illustrates a portion of his head with sample A worn thereon, FIG. 10(b)illustrates a portion of his head with sample B worn thereon, FIG. 11(a)illustrates a portion of his head with sample C worn thereon, andillustrated in FIG. 11(b) illustrates a portion of his head as sample D(with no securing member worn thereon).

Likewise, FIGS. 12(a) and (b) and FIGS. 13(a) and (b) illustrate theresults of hair inspection for subject 2 (46 years old female). FIG.12(a) illustrates a portion of a head with sample A worn thereon, FIG.12(b) illustrates a portion of a head with sample B worn thereon, FIG.13(a) illustrates a portion of a head with sample C worn thereon, andFIG. 13(b) illustrates a portion of a head as sample D (with no securingmember worn thereon).

Subject 1 had his hairs placed in a good condition without disturbancein his scale-like pattern before wearing sample A. His hairs maintaineda good condition even after the lapse of 5 hours since wearing, and thepresence of disturbance in his scale-like pattern was not substantiallyconfirmed even after the lapse of 10 hours since wearing (see FIG.10(a)).

Subject 1 had his hairs place in a good condition without disturbance inhis hairs before wearing sample B. His hairs maintained a goodconditions even after the lapse of 5 hours since wearing, and thepresence of disturbance in his scale-like pattern was not substantiallyconfirm even after the lapse of 10 hours since wearing (see FIG. 10(b)).

Although subject 1 had his hairs placed in a good condition withoutdisturbance in a scale-like pattern before wearing sample C, thepresence of disturbance in a scale-like pattern (black and hole-likeopen portions in a hair shown in FIG. 11(a)) became noticeable after thelapse of 5 hours since wearing, and the disturbance in the scale-likepattern became finer after the lapse of 10 hours since wearing (see thisFIG. 11(a)).

The inspection before wearing the respective samples revealed thatsubject 1 had his hairs as sample D placed in a good condition withoutdisturbance in the scale-like pattern. The hairs maintained a goodconditions even after 5 hours since wearing. After the lapse of 10 hourssince wearing, the scale-like pattern became easily to be visuallyrecognizable in a few portions, though definite disturbance was causedin the scale-like pattern (see FIG. 11(b)).

When sample A, sample B and sample C worn by subject 1 are compared tosample D based on the inspection results described above, it is revealedthat almost no significant difference is recognized between sample A andsample D in terms of disturbance in the scale-like pattern, and thatwearing sample A would not lead to damage in the hair cuticle.

It is revealed that almost no significant difference is recognizedbetween sample B and sample D in terms of disturbance in the scale-likepattern, and that wearing sample B would not lead to damage in the haircuticle.

It is revealed that a significant difference is recognized betweensample C and sample D in terms of disturbance in the scale-like pattern,and that wearing sample C would not lead to damage in the hair cuticle.

Before wearing sample A, subject 2 had her hairs below this samplewholly placed in a good condition, though a black noticeable disturbancein the scale-like pattern was recognizable at an extremely small numberof positions. After the lapse of 5 hours since wearing, it is confirmedthat the scale-like pattern became easy to be visually recognizable in afew positions, though no definite disturbance was caused, and that herhairs had maintained the same condition even after the lapse of 10 hourssince wearing (see FIG. 12(a)).

Before wearing sample B, subject 2 had her hairs below this sampleplaced in such a state that a scale-like pattern became easy to bevisually recognizable in a few positions, though the hairs were whollyplaced in a good condition. Her hairs had maintained the same conditioneven after the lapse of 5 hours and after the lapse of 10 hours sincewearing (see FIG. 12(b)).

Before wearing sample C, subject 2 had her hairs subjected to nodisturbance in a scale-like pattern and placed in a good condition. Incontrast, disturbance in the scale-like pattern became noticeable in ablack irregular manner in an image after the lapse of 5 hours sincewearing, and the scale-like pattern was further disturbed after thelapse of 10 hours since wearing (see FIG. 13(a).

The inspection made before wearing these samples revealed that subject 2had her hairs as sample D subjected to no disturbance in the scale-likepattern and placed in a good condition. Her hairs had maintained thesame condition even after the lapse of 5 hours since wearing. After thelapse of 10 hours since wearing, the scale-like pattern became easily tobe visually recognizable at a few positions (see FIG. 13(b)).

When sample A, sample B and sample C worn by subject 2 are compared tosample D based on the inspection results described above, it is revealedthat the same results as those for subject 1 were obtained.

The results of the scalp inspection by use of a microscope will bedescribed in reference to FIG. 14(a) to FIG. 17(b).

FIGS. 14(a) and (b) and FIGS. 15(a) and (b) illustrate the results ofthe scalp inspection of subject 1 (50 years old male) by use of themicroscope. FIG. 14(a) illustrates a portion of his head with sample Aworn thereon, FIG. 14(b) illustrates a portion of his head with sample Bworn thereon, FIG. 15(a) illustrates a portion of his head with sample Cworn thereon, and FIG. 15(b) illustrates a portion of his head as sampleD (with no securing member worn thereon).

Likewise, FIGS. 16(a) and (b) and FIGS. 17(a) and (b) illustrate theresults of the scalp inspection for subject 2 (46 years old female) byuse of the microscope. FIG. 16(a) illustrates a portion of her head withsample A worn thereon, FIG. 16(b) illustrates a portion of her head withsample B worn thereon, FIG. 17(a) illustrates a portion of her head withsample C worn thereon, and FIG. 17(b) illustrates a portion of her headas sample D (with no securing member worn thereon).

The scalp of subject 1 was subjected to no change, such as a scratch orrough skin, from before wearing sample A to after the lapse of 10 hourssince wearing (see FIG. 14(a)).

Likewise, the scalp of subject 1 was subjected to no change, such as ascratch or rough skin, from before wearing sample B to after the lapseof 10 hours since wearing (see FIG. 14(b)). The same was true for sampleC and sample D (see FIG. 15(a) and FIG. 15(b)).

In other words, when sample A, sample B and sample C worn by subject 1are compared to sample D based on the inspection results describedabove, it is revealed that no significant difference is recognizedbetween any one of samples A, B and C and sample D, and that wearingsample A, sample B and sample C would cause no problem in his scalp.

The same is true for subject 2, and scalp was subjected to no change,such as a scratch or rough skin (see FIG. 16(a) to FIG. 17(b)). In otherwords, as in subject 1, when sample A, sample B and sample C worn bysubject 2 are compared to sample D based on the inspection resultsdescribed above, it is revealed that no significant difference isrecognized between any one of samples A, B and C and sample D, and thatwearing sample A, sample B and sample C would cause no problem in herscalp.

Now, the results of their scalp inspection by use of the thermographycamera will be described in reference to FIG. 18(a) to FIG. 21(b).

FIGS. 18(a) and (b) and FIGS. 19(a) and (b) illustrate the results ofthe scalp inspection for subject 1 (50 years old male) by use of thethermography camera. FIG. 18(a) illustrates a portion of his scalp withsample A worn thereon, FIG. 18(b) illustrates a portion of his scalpwith sample B worn thereon, FIG. 19(a) illustrates a portion of hisscalp with sample C worn thereon, and FIG. 19(b) illustrates a portionof his scalp as sample D (with no securing member worn thereon).

Likewise, FIGS. 20(a) and (b) and FIGS. 21(a) and (b) illustrate theresults of the scalp inspection for subject 2 (46 years old female) byuse of the thermography camera. FIG. 20(a) illustrates a portion of herscalp with sample A worn thereon, FIG. 20(b) illustrates a portion ofher scalp with sample B worn thereon, FIG. 21(a) illustrates a portionof her scalp with sample C worn thereon, and FIG. 21(b) illustrates aportion of her scalp as sample D (with no securing member worn thereon).

In FIG. 18(a) to FIG. 21(b), areas having a cool temperature are shownin black while areas having a warm temperature are shown in white.

It was confirmed that Subject 1 had not only areas having a cooltemperature but also areas having a warm temperature on his scalp frombefore wearing sample A to after the lapse of 10 hours since wearing(see FIG. 18(a)).

It was confirmed that although subject 1 had not only areas having acool temperature but also areas having a warm temperature on his scalpbefore wearing sample B, his scalp was largely occupied by areas havinga warm temperature after the lapse of 5 hours since wearing, and thistrend was true for his scalp after the lapse of 10 hours since wearing.

It was confirmed that Subject 1 had not only areas having a cooltemperature but also areas having a warm temperature on his scalp frombefore wearing sample C to after the lapse of 10 hours since wearing.His scalp was, if anything, largely occupied by areas having a cooltemperature after the lapse of 5 hours since wearing and after the lapseof 10 hours since wearing (see FIG. 19(a)).

It was confirmed that Subject 1 had not only areas having a cooltemperature but also areas having a warm temperature on a portion of hisscalp as sample D from before wearing the other samples to after thelapse of 10 hours since wearing the other samples as in sample A andsample C (see FIG. 19(b)).

When sample A, sample B and sample C worn by subject 1 are compared tosample D based on the inspection results described above, it isconfirmed that although a difference in temperature is recognizedbetween sample A and sample D, almost no significant difference isrecognized between these samples in that his scalp had not only areashaving a cool temperature but also areas having a warm temperature.

It was revealed that a significant difference was recognized betweensample B and sample D, and that the areas having a warm temperature werecontinuously at warm temperatures on the portion of his scalp withsample B worn thereon.

It was confirmed that although a difference in temperature wasrecognized between sample C and sample D, almost no significantdifference was recognized between these samples in that his scalp hadnot only areas having a cool temperature but also areas having a warmtemperature.

In other words, when sample A, sample B and sample C worn by subject 1are compared to sample D based on the inspection results describedabove, it is revealed that the areas having a warm temperature werecontinuously at warm temperatures on the portion of his scalp withsample B worn thereon. It is assumed that sample B enhanced the bloodflow in the portion of his scalp with sample B worn thereon.

Subject 2 had not only areas having a cool temperature but also areashaving warm temperature on her scalp from before wearing sample A toafter the lapse of 10 hours since wearing the samples (see FIG. 20(a)).

It was confirmed that although subject 2 had not only areas having acool temperature but also areas having a warm temperature on her scalpbefore wearing sample B, the areas having a warm temperature wereincreased after the lapse of 5 hours since wearing, and this trendbecame further significant after the lapse of 10 hours since wearing(see FIG. 20(b)).

Subject 2 had not only areas having a cool temperature but also areashaving a warm temperature on her scalp from before wearing sample C toafter the lapse of 10 hours since wearing. Her scalp was, if any,largely occupied by areas having a cool temperature after the lapse of 5hours since wearing and after the lapse of 10 hours since wearing (seeFIG. 21(a)).

It was confirmed that subject 2 had not only areas having a cooltemperature but also areas having a warm temperature on the portion ofher scalp as sample D from before wearing the other samples to after thelapse of 10 hours since wearing the other samples as in sample A andsample C (see FIG. 21(b)).

When sample A, sample B and sample C worn by subject 2 are compared tosample D based on the inspection results described above, it wasconfirmed that the same trend as subject 1 was applied, and that wearingsample B was allowed to maintain warm temperatures of the areas having awarm temperature on the portion of her scalp with sample B worn thereon.It is assumed that wearing sample B enhanced the blood flow in a scalp.

The following conclusion are suggested by the results described above:

(1) A securing member, which has a surface coated with a siliconematerial as in sample C without the application of another coating madeof silk powder or far-infrared ray ore powder as in the above-mentionedsample A or sample B, could damage a hair cuticle as rigid keratin,depending on the hardness of the silicone material or the surface shapeof the securing member.

(2) It is possible to appropriately control the damage of the cuticle byapplying a securing member with a silk coating.

(3) It is considered that it is possible to appropriately control thedamage of the cuticle and enhance the blood flow in a scalp byapplication of a coating made of far-infrared ray ore powder. The bloodflow in a scalp can be enhanced to appropriately supply hairs withnutrition, with the result that it is expected to prevent hair loss andpromote hair growth.
